Materials needed and advice

Been away for a few years; marriage, house, babies. I restored FS # 877 to MINT (12) years ago and a few years after that got knocked down in a fast moving, ocean squall and one side of the boat was smashed to smithereens against a dock - lost my sails etc... Think large Great White ate 60% of one side of the boat... Needless to say, it was very disheartening.

Recently, I have been sailing on a buddy's Scot and have set my sites on mine again. She has been safely stored all these years.

I have already done all the structural repairs myself, now she just needs a little fairing and then a paint job...

Being out of the loop, a lot has changed since I was sailing the FS and ordering materials from Erik and Dee, via faxes and phone calls.

I want to re-install floatation under the seats - I removed all the old styrofoam stuff, it's all intact, but was hoping to replace with the blue, dock building foam - anyone have an opinion on this change and a line as to where I can buy it for the best price ?

Also, I have the older, non-anodized aluminum mast/winch halyard 'spools' that have oxidized to useless. Is there a way to replace these with newer ones ?

Sails - I see a lot more options about loose and tight fit set-ups. I have no idea if I have a loose or tight rig, or if I really care which I end up with. I just sail and don't race anyone but the wind. How can the different rigs / sails be ID ?

Thank you...

Not to long ago, I looked into a lot of this when considering restoration of a water logged sunfish.

What you are asking about is this stuff:

This is known as extruded polystyrene as opposed to the older, expanded polystyrene (the type made up of the little beads all pressed together).

The extruded stuff has much better moisture and water resistance than the expanded stuff.

In a boat like a sunfish, there are two main considerations: strength and water resistance.

The internal foam is a major part of the structure of a sunfish, but to the best of my knowledge, it provides no structural support for the Flying Scot. Also, because of the sealed nature of a sunfish hull, the foam has a greater tendency to absorb moisture than the foam in an open framework like a Flying Scot would.

Given that, there is no real reason why you could not simply use the blue foam commonly sold at Home depot type stores. The two inch thick foam is relatively cheap and you can simply use a fine cut Japanese saw to cut strips to the desired width. There are adhesives formulated for the foam that don’t contain solvents so that you could build up a block of foam with the required number of strips.

This topic brings up a question that has puzzled me.

Why a buoyancy bag?

It would be relatively simpler and probably much more reliable to fashion a block of foam that would sit on the bottom of the bow. You could create a preformed fiberglass shelf with tabs that could hold the foam in place thus you wouldn’t have to worry about the bag getting punctured. A foam block down low in the bow would be better at improving the bow buoyancy since it could be fashioned to displace more water from the lower portion of the bow. The weight difference would be negligible.

I think it is mainly because such a setup would be more work to install and would have to ship in a big box.

The bag is easy to ship, and easy to install.

Just my guess,

Actually from a refit I agree with you. Plus it may need to be in two parts to get past the stanchion. However on new boats I think it would be a good idea if the class allows it to have the foam. It won' deflate or get punctured with a spin pole. It can be glass strapped like the foam under the seat. I would believe it will be less expensive too.

1. I beleive the class rules require a minimum amount of floatation at the bow. I plan to install blue foam when I get around to it. An inflatable bag per se is not required
2. The extruded polystyrene blue foam and the pink foam is the same stuff and you can get them at the major hardware stores , Home Depot etc, sold as insulating foam.
3. I put a small piece of pink foam and submerged it in a bottle for a few weeks. There was no sogginess when I pulled out the sample.
4. You can glue the pink (or blue) foam with Gorilla glue
5. The pink and also the blue foam is compatible with epoxy resin, not with polyester.

The bow bag is required for those who plan to race sanctioned events such as the mw's, nac's and districts.

FS 5516
Don't Panic

Per S-11 8. Buoyancy
In addition, effective January 1, 2009, the boat shall include a nominal 4.8 cubic feet of buoyancy to facilitate the rescue of a swamped boat. This buoyancy shall be composed of a choice of an air bag, rigid noncommunicating air cell foam plastics or air tanks and shall be attached inside the hull at the bow as low and far forward as possible to provide a nominal 300 pounds of buoyancy when submerged in water. It shall be securely fastened so as not to become dislodged when submerged.(November 2007) (See also CMR #29 & 79)

As pointed out in the President Letter the requirement for bow bags and transom ports was added to the Specifications as the requirement by a vote of the FSSA Membership at the 2007 NAC. This change is mandatory for all boats effective on 1/1/2009. Boats that intend to participate in the 2009 Midwinter Championship, the North American Championship and the Wife Husband Championship need to make a special effort to install these items, as they will be checked at these events and others. These venues are known to be windy and installation of this equipment will facilitate rescue and recovery in the event of a capsize. The kits for these items, including the appropriate hole saw, will be available from Flying
Scot Inc. at these regattas for installation on site. Please note that the builder of the Flying Scots has installed these as standard equipment on new boats manufactured since 1992.

Somewhat confusing, but I believe the intent is to have 300 lbs of buoyancy. Maybe Bob Neff will clarify?

I was hoping to put some of the blue 'dock floatation' instead of the 1960's ( literally ) styro-foam.


Also, anyone have info on restoring the aluminum spools on the older main and jib halyard winch assembly's ? Mine need to be replaced...


Lastly, how can I determine what 'fit' sails I have ? My sails were trashed and I bought a new set of used ones online. I'm assuming my boat is rigged for cruising / loose fit - but don;t know what the cut is on these replacement sails...

Do you know who the sailmaker was for your replacements? If so, I would call them. They can tell you how to set the rig.

Also Harry at Flying Scot Inc, can probably give you good advice.

The mains are all more or less the same. The following link leads to information about how to determine which rig your jib is cut for:,rig

I always wondered whether these measurements also applied to sails that were not made by North Sails.

Anybody know?
